6. MAINTENANCE OF HORIZONTAL SPLIT CASE PUMPS

6.1. LUBRICATION

6.1.1 COUPLINGS: Couplings with rubber drive elements do not require lubrication.
6.1.2 BEARINGS: Care and maintenance of bearings is a matter of ensuring that they are:
 Correctly lubricated at intervals a laid down in routine maintenance chart.
 Thoroughly clean grease fitting and outside of bearing housing
 Remove drain plug
 Inject clean, new grease forcing out the old.
 Start and run the pump for a short time to eject any excess grease.
 Wipe off all excess grease and replace drain plug.
 Tool used and work areas should be cleaned
 To remove the bearing ,use correctly suited withdrawal equipment
 Damage can be caused by exerting force against the outer ring of ball bearing. Ball
bearings should not be dismantled. Clean bearings thoroughly with an approved
fluid. Dry the bearings by spinning with dry compressor air of by hand. Do not spin a
clean dry bearing. Inspect the bearing for wear, fracture, cracks, corrosion or other
damage which may necessitates bearing replacement. Pack both sides of bearing
with grease. Check that the bearing, shaft and housing are cleaned and un
damaged. Recharge with grease to a maximum of two thirds full. Refit the bearing
onto the shaft and press for tap into position.

6.1.3 BEARINGS DETAILS:

The pumps are fitted with antifriction heavy duty ball bearings at driving and non
driving ends. The detail of bearings is as under.

6.1.4 LUBRICATION DETAILS:

Normally pumps are shipped with a high quality, lithium soap base, ball and roller bearing
grease filled bearings only. Regreaseing interval depends upon the operating speed of the
unit.
